Abstract Value Members

  1. abstract def doFork(runnable: () ⇒ Unit, name: Option[String], region: Option[Region]): AbstractTesterThread
  2. abstract def doJoin(threads: Seq[AbstractTesterThread], stepAfter: Option[Clock]): Unit
  3. abstract def doTimescope(contents: () ⇒ Unit): Unit
  4. abstract def expectBits(signal: Data, value: BigInt, message: Option[String], stale: Boolean): Unit
  5. abstract def getSinkClocks(signal: Data): Set[Clock]

    Returns set of clocks associated with sinks of the signal

  6. abstract def getSourceClocks(signal: Data): Set[Clock]

    Returns set of clocks associated with sources of the signal

  7. abstract def peekBits(signal: Data, stale: Boolean): BigInt

    Returns the current value on a wire.

    Returns the current value on a wire. If stale is true, returns the current combinational value (after previous pokes have taken effect). If stale is false, returns the value at the beginning of the current cycle.

  8. abstract def peekClock(signal: Clock): Boolean

    Read the value of a clock.

  9. abstract def pokeBits(signal: Data, value: BigInt): Unit

    Writes a value to a writable wire.

    Writes a value to a writable wire. Throws an exception if write is not writable.

  10. abstract def pokeClock(signal: Clock, value: Boolean): Unit

    Writes a value to a clock.

  11. abstract def setTimeout(signal: Clock, cycles: Int): Unit

    Sets the timeout of the clock: the number of cycles the clock can advance without some non-nop poke operation.

    Sets the timeout of the clock: the number of cycles the clock can advance without some non-nop poke operation. Setting cycles=0 disables the timeout. Setting cycles=1 means every cycle must have some non-nop poke operation. Resets the idle counter associated with the specified clock.

  12. abstract def step(signal: Clock, cycles: Int): Unit

    Advances the target clock by one cycle.
